This section is distal to the carpal canal. The thenar (2, 5, 6) and hypothenar (24, 25, 27) muscles dominate the medial and lateral palmer surface of the hand. Palmaris longus tendon (1) has begun to expand to form the palmer aponeurosis. The distal edge of palmaris brevis (28) is seen for the last time.

The bases of the metacarpal bones can be seen. Note that the fifth (22), fourth (17), third (15), and second (12) metacarpal bones articulate with each other at their bases and that the first (8) articulates only with the trapezium. The dorsal (16) and palmer (13) metacarpal ligaments are seen.
